Abstract
After the text document in the file directory is opened through the application software of the host, the host reads the file name, the current page number and the page sliding position information of the current text document in real time in the process of page turning or sliding of the text document, and distributes the information to the authorized slave end in real time through the communication network. After receiving the information sent by the host computer, the slave computer firstly judges whether the document is opened; if the document is not opened, the slave terminal searches and opens the document in the file directory. Then, the page number and the page sliding position of the document at the slave end are adjusted to keep the document at the slave end and the document at the master end synchronous. When the document at the host end is paged, the document at the slave end is paged synchronously; when the document at the host end slides up and down, the document at the slave end synchronously slides up and down. Therefore, the synchronous page turning device helps students synchronously turn pages of documents on a computer, and avoids the dispersion of attention caused by frequent page turning during the course of listening to the students.
